specIAl non-sHocK MecHAnIsM
Starrett dial indicators have hardened, stainless steel gears, pinions and racks for maximum resistance to
shock. Where the rack is subject to repeated, severe and/or excessive mechanical shocks, many Starrett
AGD dial indicators may be ordered with a special non-shock mechanism. Based on a positive-loaded, split
gear assembly, this simple device protects indicator accuracy, prolongs life, and reduces service costs.
When ordering, specify "N/S" after the dial indicator catalog number.
The following indicators are not available with non-shock mechanism: 25-109, 25-209, 2600 and 2700
Indicators; 656-109, 656-209 and all other indicators with 2" (50mm) range and above.
